Identify what the document establishes and the actual subsequent transactions. Avoid presenting a past sale agreement as a complete account of funds it does not track.
Retain the filed case, investment and transfer records, immigration notices and status documents, plus relevant project reports and supporting evidence obtained through the appropriate process. For a gift, produce a signed gift instrument, evidence of how the donor lawfully acquired the funds, and the transfer record; a gift letter without the donor's financial history leaves a gap in the lawful-source evidence. For lawful source, the file goes back further: how the investor originally acquired the industrial-supply firm's shares, whether by founding it, buying it or inheriting it, with corporate records and personal tax returns from that period. If purchased, the original purchase agreement and how that purchase was funded, whether by a professional loan since repaid; if built from scratch, the incorporation records, early financial statements and the loans or savings that started it.
